A New Mars

A New Mars
A New Mars Socrates declared he knew nothing except the fact of his ignorance. Indeed, when it comes to Mars, the more we see, the less we understand, thus realizing the extent of our ignorance. This Mars Orbiter Laser Altimeter (MOLA) image of the Red Planet’s Argyre Planitia was produced by combining MOLA altimetry with color from a Viking image mosaic. The Argyre impact basin, measuring 1,200 kilometers (about 745 miles) in diameter, formed when a large object struck Mars about 4 billion years ago. MOLA science team and G.
